Hello guys, i want to ask about the bug on my Louis Files. When i first wear custom wing like Conqueror wing it will not show visually the wing. but when i re-equipped it the wing will appear. Also if im going to remove any items i wear the wing will disappear again same as when im swtiching character.

Might be a dumb question but, did you reloaded your GS- Custom ? I was having the exact same problem and then noticed i forgot to reload custom and that's it.

I've experienced this before. When you install a custom wing, the login might not recognize the wing. Once inside, you have to remove the wing and put it back on.
Only then will the wing be recognized.
You should check your ViewPort in GS Source
It just hasn't been declared yet. It took me quite a while to discover it.
